KikiCreates turns a plain cardboard box into something a kid will play with for hours.
Wait, they already play with cardboard boxes for hours. In fact, as I write this, my daughter is playing with a box that she's been hauling around all week saying, "Okay toys, I'm giving you to Andy." Maybe we should lay off the Toy Story 3.
The difference between a regular cardboard box and this transformed one is that it LOOKS like something kids should play with.And it's totally awesome.
No tutorial, but some more details from Kiki Creates here.
